Has anyone thought about or implemented a exclusionary message list,
such as:

ausearch -m ALL-avc,user_avc -ts today

Actually in this case I'm running the search from a script so I can
easily take the stderr results from "ausearch -i -m help", pipe them
into a sed substitution which removes the preceding text, removes the
ones I don't want, and replaces the spaces with commas.
So for now I am set; still I think it would perhaps be helpful to have
at some point.
